DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attractive porous poison bait for termites that exterminates underground termites.

[0002]

2. Description of the Related Art At present, generally used termite poison baits such as so-called blocks having a solid shape and a dense inside (mud body) or granular or paste-like materials are packed in a cylindrical container. Are the mainstream.

[0003]

However, in any case, the termite bait having the above-described structure has a small effective area in which termites can be attacked because of its solid shape with a dense interior. It is difficult to give a large amount of termites a lethal dose of bait in a short time. For example, it takes too long to destroy a colony. In addition, conventional termite poison baits often use mainly quick-acting drugs, so that when the first termite that eats the bait begins to die, other termites are dangerous because some pheromone is emitted from the termites. And it stops eating the poison bait, so complete extermination is not possible.

In view of the above circumstances, the present invention provides a corrugated cardboard porous paper aggregate using a slow-acting insecticidal component impregnation and an attractive adhesive so that a large amount of termites can attack a poison bait in a short time. It is an object of the present invention to provide an attractive porous poison bait for termites which solves the above-mentioned problems by combining this with a water-impermeable film.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a corrugated core paper portion impregnated with a slow-acting insecticidal component and a liner paper portion impregnated with a slow-acting insecticidal component. At the same time, the bonded portion of the corrugated core paper portion and the liner paper portion is bonded with an adhesive having a termite-inducing effect, such as corn starch, sweet potato starch paste, etc., to form a corrugated cardboard body. An appropriate number of wave holes are vertically stacked to form a corrugated cardboard laminate to form a porous paper aggregate of a predetermined shape, and a non-water-permeable film is applied to the entire area except the bottom surface where the wave hole end of the porous paper aggregate faces. The cover is a high-humidity hollow type.

[0006] The porous paper aggregate is a cylindrical body in which a long single-sided corrugated cardboard body is spirally wound.

Further, the porous paper aggregate is a prismatic body in which a large number of rectangular single-sided cardboard bodies are laminated.

[0008]

As described above, the attractive porous poison bait for termites eats corrugated core paper and liner paper impregnated with a slow-acting insecticidal component.
A corrugated cardboard body is glued with an adhesive having a termite attracting action, such as sweet potato starch paste, and the corrugated paperboard body is made into a corrugated cardboard laminated body with the wave holes oriented vertically. Because the structure is covered with the water-impermeable film, if the bottom surface of the opening is directly placed on the ground, moisture in the ground penetrates and moves into the cardboard ground, and the porous paper aggregate is humidified. For this reason, termites that prefer high humidity are attracted to the inside by the attraction of the adhesive (glue) and the moisture.
In this case, since the corrugated cardboard body has a structure in which a number of vertical holes reaching the bottom from the ceiling, the termites can easily penetrate each wave hole, the effective area where termites can attack increases, and a large amount of termites are contained inside. It can be drawn all at once. The termites that have invaded the inside instinctively eat cellulose, and the glue uses corn starch and sweet potato starch glue to attract the termites, so that they eat the cardboard body impregnated with the slow-acting insecticidal component. Since the medicinal effect of this insecticidal component is slow-acting and does not die immediately but works gradually, it does not give a caution to subsequent termites that invade sequentially. Therefore, a large amount of termites can be eaten by the poison bait substantially in a short time.

[0009] Whether the shape of the attracting porous poison bait is formed into a cylindrical body, a prismatic body or the like may be appropriately selected depending on the installation location.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings of the embodiments.

FIGS. 1 to 4 show an embodiment of an attractive porous poison bait for termites in which a porous paper aggregate is formed into a cylindrical body.
Is a corrugated core paper portion 1a uniformly impregnated with a solution of a slow-acting insecticidal component 2 such as an insecticidal component hydramethylnon or an insect growth-controlling hormone (methoprene) composed of a suitably thick cellulose cardboard. A liner paper portion 1b uniformly impregnated with a solution of the insecticidal component 2 having the same delayed action is bonded by a known corrugated board process, and the adhesive 3 at the bonded portion is made of corn starch having termite attracting action.
It is a single-sided corrugated cardboard body formed using a sweet potato starch paste as a base material. In this case, the corrugated core paper portion 1a
Is set to about 3 to 5 mm in which termites can enter. The single-sided corrugated cardboard body 1 is spirally wound into a corrugated cardboard laminate 1 ′ so that the corrugated holes 4 are oriented vertically, thereby forming a porous paper aggregate 6 of a cylindrical body 5. The porous paper aggregate 6 covers the entire area of the outer peripheral surface 6b and the upper surface (ceiling portion) 6c except for the bottom surface 6a serving as the lower end opening of the corrugated hole 4 with a water-impermeable film 7. It becomes an attractive porous poison bait 8 for termites.

Next, the operation will be described. First, in forming the attracting porous poison bait 8, the single-faced corrugated cardboard body 1 is formed using a cellulose cardboard having a thickness of about 0.5 mm. In this case, the corrugated core paper portion 1 constituting the main body
a and a liner paper 1b impregnated with a slow-acting insecticidal component 2 such as hydramethylnon or an insect growth-controlling hormone, and after drying, adhesion of corn starch and sweet potato starch paste to attract termites Agent 3
To form a single-faced corrugated cardboard portion having a predetermined length, and to form a corrugated paperboard 6 of a cylindrical body 5 in a spiral shape so that the corrugated corrugated holes 4 are not crushed and the corrugated holes 4 are oriented vertically.
And Next, a synthetic resin film 7 is covered on the porous paper aggregate 6 in a cap shape except for the bottom surface 6a to form a single poison bait.

In use, the attracting porous poison bait 8 is brought into contact with the ground (soil surface) a where termites are likely to appear and emerge, with the bottom 6a of the porous paper aggregate 6 facing the large number of wave holes 4 facing downward. If placed directly, the effective surface area that termites can attack will increase enormously, and the attracting porous poison bait 8 itself is provided with a film 7 that suppresses evaporation of water and air permeability around the outside. It moves up to the porous paper aggregate 6 by evaporation or the like, and the inside of the aggregate becomes substantially the same humidity as the soil side. That is, the porous paper aggregate 6 side keeps the humidity preferred by the termites (high humidity state) (usually, as a habit of the termites, drying and ventilation are abnormally disliked). In addition, the adhesive 3 for forming corrugated cardboard is mainly composed of corn starch and sweet potato starch glue having the property of attracting termites. Gender was not seen).

Here, if termites inhabit the ground, the termites naturally gather due to the attraction of the poison bait 8 and are drawn inside from the large number of wave holes 4. The inside (corrugated cardboard body) is made of cardboard based on cellulose, which is instinctively eaten by termites, and is impregnated with the slow-acting insecticidal component 2, and is used to bond the corrugated core paper portion 1a and the liner paper portion 1b. Since corn starch and sweet potato starch glue (adhesive 3), which are preferred by termites, are used, they rob the porous paper aggregate 6 (corrugated cardboard body 1) and sequentially invade into the depths of the vertical wave holes 4, so that thousands of termites are found. A large amount of termites entering the internal space eat the porous paper aggregate 6. In this case, the drug impregnated in the porous paper aggregate 6 is the slow-acting insecticidal component 2, and the termites do not die on the spot, do not hinder the eating of the subsequent termites, and have a large amount of termites. To the whole insecticide component 2.

The termites once return to their nests as a habit, and feed the bitten food to larvae, soldiers, etc., so that the slow-acting insecticidal components work in the nests and die. That is, the termites do not die while eating the bait (the attractant porous poisonous bait 8) and return to the nest, and feed the other termites in the nest, so that the slow-acting insecticidal component 2 spreads in sequence, leading to death. In this way, a long-acting insecticidal component is given to a large number of termites in a short period of time, and when death occurs in the nest, the balance in the nest is lost, and microorganisms such as molds proliferate abnormally and the nest is completely annihilated.

FIGS. 5 and 6 show another embodiment in which the porous paper aggregate is a prismatic body. In this case as well,
A rectangular single-sided corrugated cardboard body 1 is formed by a rectangular corrugated core paper portion 1a impregnated with a slow-acting insecticidal component 2 and a liner paper portion 1b, and the adhesive 3 used for the bonding portion is formed by the aforementioned method. Similarly, corn starch and sweet potato starch paste having a termite-inducing effect are used. Further, a large number of single single-faced corrugated cardboard bodies 1, and the corrugated holes 4 are vertically stacked to form a corrugated cardboard laminate 1 ′ to form a porous paper aggregate 6 of prismatic bodies 9. The corrugated holes 4 of the porous paper aggregate 6
Outer peripheral surface 6b and upper surface (ceiling part) excluding bottom surface 6a facing the end
When the non-water-permeable film 7 is covered over the entire area of 6c, a humidified hollow termite-inducing porous poison bait 8 having a prismatic shape is obtained.

In the same manner as described above, when the prismatic inductive poison bait 8 is used, if it is placed directly on the ground with the bottom of the opening facing down, moisture in the soil is sucked up by the porous paper aggregate 6 and the inside is absorbed. It becomes humid. For this reason, the termites are attracted by the high humidity and the attraction of the adhesive 3 and penetrate into the inside, and by eating the porous paper aggregate 6, the slow-acting insecticidal component 2 is taken into the body, and the termites enter the nest as described above. You will die after returning.

Since the form of the attracting poison bait 8 of the prismatic body is a long one having a predetermined length, it can be arranged along the foundation of the building, and the appearance is good.

[0019]

As described above, the attractive poison bait for termites of the present invention is based on corrugated paper, which is preferred by termites, impregnated with a slow-acting insecticidal component, and is provided with a termite-forming adhesive. The cardboard body is spirally or simply laminated using an attractive glue, and the periphery except the bottom surface is covered with a water-impermeable film to form a single unit. Therefore, a simple set in which the bottom surface is simply placed on the ground when used is sufficient. In this case, the inside can maintain an environment (high humidity) suitable for termite inhabitation, and a porous paper aggregate (for example, a porous paper aggregate unit having a size of 10 cm in diameter × 20 cm in height)
Each of the vertical holes is a space where thousands of termites can enter, so that a large amount of termites can be efficiently collected in a short time, and the base material is easy to bite for corrugated paper, providing a slow-acting poison bait. Can be The termites that return to the nest as a habit can be fed to other termites, such as feeding them with a slow-acting poison bait, causing the death of the termites in turn, disrupting the balance of the termites in the nest and destroying the nest. Further, the attracted porous poison bait is advantageous in that the substrate can be easily formed at low cost by molding using a corrugated cardboard to perform swirling, lamination, and the like.
